The potential spoiler comes from... Audi?

Marvel is keeping tight-lipped on many major plot points in Avengers: Endgame, but it appears the car manufacturer Audi may have inadvertently revealed who attempts to rescue Iron Man from space.

Spoiler warning: potential spoilers for Avengers: Endgame ahead.

As reported by CBR, at this year’s CES in Las Vegas, Audi is presenting an "in-car VR experience” which integrates car movement with what is being displayed on a VR headset in the backseat. The experience, officially called Marvel’s Avengers: Rocket’s Rescue Run, was developed by Disney Games and Interactive Experiences. It has the movements of the Audi translated as a spaceship’s movements being piloted through an asteroid field by Rocket Raccoon.

Of course, this marketing integration between Disney and Audi may have nothing at all to do with Endgame or the rescue of Tony Stark. However, Audi and Iron Man have been connected since the original MCU film was released in 2008 with the appearance of an Audi R8. What’s more, last month Audi introduced the Audi e-tron GT Concept with the help of none other than Robert Downey Jr., saying the vehicle will make an appearance in Endgame.

“I [drove the car] as Tony Stark in Avengers 4, out in theaters Spring 2019,” said Downey Jr. This alone alludes to Stark managing to survive his ordeal in space and make it back down to Earth. After all, there aren’t any Audi’s floating in space - even if a Tesla Roadster has had the privilege.

The first Endgame trailer showed us a desperate Tony Stark floating adrift in space, with no food or water left, nearly out of oxygen and almost no hope of survival.

Of course, if the name "Rocket’s Rescue Run" does directly tie into the plot of Endgame, he could also be attempting to rescue Ant-Man from the Quantum Realm - though because of the humorous ending of the movie’s first trailer, we know had managed to somehow escape regardless.
